I had created a new rule under Default Barcode Nomenclature as 99.....{NNNDD} with type as priced product and Encoding as EAN-13.

Then I created a product with it's barcode as 22301. In theory, whenever I scan " 9922301006554" in Odoo PoS, it should add product 22301 with price 6.00 to the current sale. But, it doesn't do that. I tried 22301 in both barcode and internal-reference field, but no go.
